Design Options


At Trade Price Warmer Living, we put the design of your extension fully in your hands but with our advice along the way.

Thanks to our huge range of customisation options, you can tailor your extension down to the smallest detail. From selecting the roof style to choosing the colours of your cladding, you have the freedom to personalise your extension as much or as little as you like.

Do you prefer a traditional pitched roof or a neat, minimalist flat roof? Bright or muted colours? Slate or shingle tiles? Whatever your vision, we’ll make it a reality.

Below, we’ve explored all the options available for designing your extension. If you have any questions, feel free to get in touch with our team – we’ll be happy to explain our options in more detail. You can also learn more by browsing our downloadable brochure.

Roof Design Options

Thanks to our revolutionary pod system, our extensions can adapt to any pitched or flat roof style you can think of!


A classic shape made up of three sides sloping towards the ridge.

Edwardian hipped

Similar to the Edwardian, but with four sides instead of two. Comes with an aluminium box gutter.


A simple, mono-pitched roof that offers clean lines. Perfect for adding large opening vents.

Lean-to side hipped

Same shape as a lean-to, with the addition of two hips creating two extra sloping sides.


A contemporary look with two sides sloping towards the ridge. You can choose to add a glass gable frame to the front to maximise natural light.

Flat roof

A flat, even roof with no slopes or pitch. Minimalist, modern, and timelessly stylish.

Vaulted Ceilings

Our structurally engineered steel corner braces are concealed within the framework, eliminating the need for structural trusses, tie bars, or tie wires on any pitched roof measuring up to 5 x 5 metres. Enjoy a clean, unobstructed ceiling and plenty of extra headroom!

Roof Colours and Materials

Slate Tiles

We use Britmet’s LiteSlate, a cutting-edge synthetic slate roofing tile made from 90% recycled polymers. This remarkable innovation embodies all the qualities you would expect from a traditional slate tile, without the cracking, breaking, or chipping that normal slate can suffer from.

LiteSlate combines an authentic riven-edged finish with a range of classic colour options. Not only does it capture the timeless beauty of slate, but it’s also made from highly sustainable materials.

Shingle Tiles

We use Britmet Shingle tiles, which stand out as having the widest standard colour range available in the UK. They’re almost indistinguishable from traditional American shingle, but with a unique twist: they feature a full dry-fix, interlocking hidden-fix design, allowing for a flush roof surface without visible fixings.

  • Tick in a Circle Icon BlueFire rated to AA classification

We supply double-ogee gutters that are available in one of four colours: white, brown, grey, or black. Choose the one that matches your home’s existing gutters for a truly seamless look!


Our fascias are available in two stunning finishes: plain white or woodgrain. Our woodgrain fascias come in a variety of colours and are designed to resemble real timber, offering an authentic look that’s almost indistinguishable from the real thing.

Cladding Colours

Benefits of Freefoam Cladding

Tools Icon Red and White

Easy to Install

All of Freefoam’s cladding products are easy to fit. Whether you opt for the standard PVC-U range or the aluminium range, their fitting trims are specifically designed for a hassle-free installation process.

Tick in a Cog Icon

Low Maintenance

PVC is well-known for its stability and low maintenance. Cladding products made from PVC are exceptionally durable and long lasting, so there’s no need for frequent repainting or maintenance. Maintaining their appearance is as simple as giving them a quick wipe-down with a damp cloth.

Design Flexibility Icon


Freefoam cladding is incredibly versatile, making it a perfect choice for all types of exteriors, including brick, masonry, and concrete. It effortlessly enhances the visual appeal of any project, whether the design is traditional or contemporary.

Home Thermal Efficiency Icon

Energy Efficient

With heating costing more than ever, exterior wall cladding is the ideal way to enhance the insulation of your home and lower your energy bills. When paired with generic insulation materials, PVC cladding has received an impressive A+ rating from The Building Research Establishment’s (BRE) ‘Green Guide to Specification.’ This rating not only reflects the excellent thermal performance of PVC cladding, but also highlights its eco-friendly attributes.

Window and Door Options

We have a wide range of doors available, in both contemporary uPVC and aluminium. Styles include patio, French, and bi-fold doors, each available in an array of colours. With options to suit virtually all architectural styles, you’re sure to find the perfect design for your property.

We also offer full height, pocket, and corner return windows to provide you with even more design flexibility.

Durabase System

Extension Base Options

When building your extension, you have two options: you can either retrofit it onto an existing base or choose to build it on our innovative Durabase foundation.

Durabase combines a durable steel base with modular wall construction. This winning combination allows you to build it with ease, saving you both time and effort. We also have over 40 brick slip finishes for you to choose from, so you can easily find the perfect match to complement your home’s existing masonry.
